Given:
The team typically has 25% of the players in the tryouts process come back for a second evaluation.
The team asked 17 players back for a second evaluation.
To find:
The players showed up for the first tryout.
Solution:
Let x be the number of players showed up for the first tryout.
According to the question,
[tex]25\%\text{ of } x=17[/tex]
[tex]\dfrac{25}{100}x=17[/tex]
[tex]\dfrac{1}{4}x=17[/tex]
Multiply both sides by 4.
[tex]x=17\times 4[/tex]
[tex]x=68[/tex]
Therefore, 68 layers showed up for the first tryout.

You have eight more dogs than cats. You have 2 fewer chickens than dogs. You have three fewer guinea pigs than cats. If you have a total of 59 pets, write an equation that would help you find how many of each pet you have. Describe what the variable represents (Let __ represent...).
Answer:
read the answers below.
Step-by-step explanation:
d = dog
d = c + 8
ch = chickens
ch = d -2
gp = guinia pigs
gp = c - 3
d + c + ch + gp = 59
gp = c- 3
gp = d -8 - 3
gp = d - 11
d + d-8 + d - 2 + d-11 = 59
4d -8 - 2 - 11 = 59
4d - 21 = 59
4d - 21 + 21 = 59 + 21
4d = 80
4d/4 = 80/4
d = 20
========
c = d - 8
c = 20 - 8
c = 12
========
ch = d - 2
ch = 20 - 2
ch = 18
=========
gp = d - 11
gp = 20 - 11
gp = 9

the sum of 1 and 3 times a number is 22. write and solve and equation to determine the number. select the solution and graph that represents the number
a) x=4
b) x=6
c) x=7
d) x=9
Answer:
b
Step-by-step explanation:
If the sum of 1 and 3 times a number is 22, then x=7 is the solution and graph that represents the number
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
The sum of 1 and 3 times a number is 22.
Let the unknown number be x
1+3x=22
Now subtract 1 from both the sides
1+3x-1=22-1
3x=21
Divide both sides by 3
x=7
So the solution of sentence sum of 1 and 3 times a number is 22 is 7.
x=7 is the equation of graph that represents the number
Hence x=7 is the equation of graph that represents the number

Una escalera de 131313 metros está recargada contra una pared cuando su base empieza a resbalar. Cuando la base está a 121212 metros de la pared, se mueve a una razón de 5\text{ m/s}5 m/s5, start text, space, m, slash, s, end text. En ese momento, ¿a qué razón está cambiando el ángulo \thetaθtheta entre el piso y la escalera?
Answer:
El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.
Step-by-step explanation:
Sea [tex]x[/tex] la distancia horizontal entre la pared y la base de la escalera y [tex]l[/tex] la longitud de la escalera, medidas en metros. Además, tenemos que [tex]\theta[/tex] es el ángulo entre la escalera y el piso, medido en radianes.
Si la pared y el piso son ortogonales entre sí, entonces podemos utilizar la siguiente relación trigonométrica que relaciona las variables anteriores:
[tex]\cos \theta = \frac{x}{l}[/tex] (1)
Por diferenciación implícita y la definición de razón de cambio tenemos que:
[tex]-\sin \theta \,\dot \theta = \frac{\dot x}{l}[/tex] (2)
Donde:
[tex]\dot x[/tex] - Razón de cambio de la distancia horizontal entre la pared y la base de la escalera, medida en metros por segundo.
[tex]\dot \theta[/tex] - Razón de cambio del ángulo entre el piso y la escalera, medida en radianes por segundo.
Pero tenemos que el seno del ángulo está definido por:
[tex]\sin \theta = \frac{\sqrt{l^{2}-x^{2}}}{l}[/tex] (3)
Si aplicamos (3) en (2), expandimos la ecuación como sigue:
[tex]-\frac{\sqrt{l^{2}-x^{2}}}{l}\,\dot \theta = \frac{\dot x}{l}[/tex]
[tex]\dot \theta = - \frac{\dot x}{\sqrt{l^{2}-x^{2}}}[/tex] (4)
Si tenemos que [tex]\dot x = 5\,\frac{m}{s}[/tex], [tex]l = 13\,m[/tex] y [tex]x = 12\,m[/tex], entonces la razón de cambio del ángulo es:
[tex]\dot \theta = -\frac{\left(5\,\frac{m}{s} \right)}{\sqrt{(13\,m)^{2}-(12\,m)^{2}}}[/tex]
[tex]\dot \theta \approx -1\,\frac{rad}{s}[/tex]
El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.

2. Function C takes time for its input and gives a student's Monday class for its output.
a. Use function notation to represent: A student has English at 10:00.
b. Write a statement to describe the meaning of C(11:15) = chemistry.
Answer:
We know that C(T) is a function where you input the time T, and the output will be the student's Monday class.
a) A student has English at 10:00.
Here we can use T = 10:00 as the input, and the output will be the class, English.
Then this can represent this with:
C(10:00) = English.
b) Write a statement to describe the meaning of C(11:15) = chemistry.
for C(11:15) = Chemistry
The input, the time, is 11:15
The output, the class, is chemistry.

solve (2x-10)=(65-x) show your work plz!
Answer: x=25
Step-by-step explanation:
Simplifying
(2x + -10) = (65 + -1x)
Reorder the terms:
(-10 + 2x) = (65 + -1x)
Remove parenthesis around (-10 + 2x)
-10 + 2x = (65 + -1x)
Remove parenthesis around (65 + -1x)
-10 + 2x = 65 + -1x
Solving
-10 + 2x = 65 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
-10 + 2x + x = 65 + -1x + x
Combine like terms: 2x + x = 3x
-10 + 3x = 65 + -1x + x
Combine like terms: -1x + x = 0
-10 + 3x = 65 + 0
-10 + 3x = 65
Add '10' to each side of the equation.
-10 + 10 + 3x = 65 + 10
Combine like terms: -10 + 10 = 0
0 + 3x = 65 + 10
3x = 65 + 10
Combine like terms: 65 + 10 = 75
3x = 75
Divide each side by '3'.
x = 25
Simplifying
x = 25

Two linear functions are shown below. Which function has the greater rate of change? Function A: 4 8 12. y 1 2 3 4 Function B: y= 0.75x - 2
Answer:
Function B
Step-by-step explanation:
✍️Rate of change for Function A:
Using any two pairs from the table of values given, say, (0, 1) and (4, 2):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 -x_1} = \frac{2 - 1}{4 - 0} = \frac{1}{4} [/tex]
Rate of change for function A = ¼ = 0.25
✍️Rate of change for Function B:
Equation for Function B is given in the slope-intercept format, y = mx + b.
m = slope = rate of change.
Therefore, the function, y = 0.75x - 2 has a rate of change of 0.75.
Rate of change of Function B = 0.75.
✅0.75 if greater than 0.25, therefore, Function B has the greater rate of change.
The function which has a greater rate of change or slope is required.
Function B has a greater rate of change.
Rate of change is given by
[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]
The ordered pairs for the first function are
[tex](0,1),(4,2),(8,3),(12,4)[/tex]
Slope
[tex]m=\dfrac{2-1}{4-0}=\dfrac{1}{4}=0.25[/tex]
Since, it is a linear equation the slope will be equal for all ordered pairs.
The point slope form of a line is
[tex]y=mx+c[/tex]
where
m = Slope or rate of change
c = y intercept
Here, the equation is
[tex]y=0.75x-2[/tex]
The slope is 0.75.
Function B has a greater rate of change.

Timothy has $500. He spends $50 each week on
groceries. Write an equation to find the total amount
of money he has left, y, after x weeks have passed.
Answer:
It takes 10 weeks to spend each $500
Step-by-step explanation:
If he spend $50 each week on groceries, we can say that he spend $100 on groceries every two weeks
To make it to 500 dollars we would have to use the equation 100x5.
This equals to 500
We could also do 100 plus 100 plus 100 plus 100 plus 100.

The reasonable price of the car after 4 years will be $8618.
What is regression analysis?Regression analysis is a group of statistical procedures used in statistical modelling to determine the associations between a dependent variable and one or more independent variables.
Given that a dealership tracks the correlation between the age of its used cars and asking price for a car. The regression line is y = 12,338 – 930x, where x is the age of the car, in years.
The price of the car after 4 years will be calculated as follows:-
y = 12338 - 930x
y = 12338 - ( 930 x 4 )
y = 12338 - 3720
y = $8618
Therefore, the reasonable price of the car after 4 years will be $8618.
